The YETI 30oz Rambler Tumbler w/ Magslider Lid is a large tumbler for cold or hot beverages. The stainless steel 18/8 construction with double-wall vacuum insulation is tough-as-nails for any job site, adventure, or road trip and keeps drinks cold or hot until they're gone. This sizeable cup doesn't have a handle, so it won't compete with the passenger's cupholder space. The MagSlider Lid prevents drinks from splashing out on bumpy dirt roads and makes it easy to sip when thirsty.
